750 ml Shampoo Bottle: What to Specify, and Where It Fails
By Joe Joo · 8PCK · Shantou · Updated 26 October 2026
750 ml Shampoo Bottle in HDPE: a 28/410 neck with a heavy lotion pump. The mistake to avoid is a 24/410 neck that looks undersized and doses too slowly.
750 ml Shampoo Bottle is the standard format for shampoo at this size: HDPE body, 28/410 neck, heavy lotion pump closure.
Almost every complaint in this combination traces to a 24/410 neck that looks undersized and doses too slowly — a specification decision, not a moulding defect.
The free Bottle Spec Checker tests whether your neck fits the closure and whether the wall survives a pump stroke.

Why This Combination
750 ml is the volume shampoo is normally sold in, and 28/410 is the neck that size is moulded on. The heavy lotion pump follows from the neck, which is why the closure choice is really a neck choice.
The failure we see is a 24/410 neck that looks undersized and doses too slowly.
The Neck Decides the Closure
28/410 takes the heavy lotion pump and the standard range for that neck.
Testing
The closure is fitted and leak-tested on the filled bottle before packing.
Wall, Weight and Shipping
At 750 ml the shoulder carries the load. Below 0.55 mm a pump stroke deforms it and the pump draws air; 0.65 mm where the closure is heavy.
If the pack ships filled, the carton has to support the shoulder — that is where most transit damage starts.
